5 cups chicken stock (or 4 cups stock + 1 cup water)
1 can diced tomatoes (14.5 oz), undrained
1 cup heavy cream, at room temperature

How to Make Creamy Cajun Chicken Pasta Soup

Sauté Aromatics:
Melt butter in a large Dutch oven over medium-high heat. Add onion and garlic, cooking for about 5 minutes until soft and fragrant. Stir in 1 tbsp Cajun seasoning.
Add Liquids:
Remove pot from heat briefly and stir in the chicken stock, diced tomatoes (with juices), and heavy cream. Return to heat and bring to a gentle boil. Reduce to a rapid simmer.
Cook Pasta:
Add dry pasta to the soup and stir frequently. Let simmer for 10 minutes, stirring occasionally so nothing sticks.
Cook the Chicken:
Coat the chicken evenly with the remaining Cajun seasoning. Heat oil in a skillet over medium heat. Cook chicken for 3–5 minutes per side until golden and cooked through. Rest briefly, then chop into bite-sized pieces.
Finish the Soup:
Reduce soup to low heat. Stir in parmesan until melted and creamy. Add chopped chicken and simmer another 2–3 minutes.
Season and Serve:
Taste and adjust seasoning with salt and pepper. Ladle into bowls and garnish with sliced green onions.

Tips to Make It Even Better

Use freshly grated parmesan for the smoothest melt and best flavor.
Watch your pasta as it can overcook easily in soup. Al dente is your friend.
For extra heat, toss in a pinch of red pepper flakes.
Swap the pasta: Shells, rotini, or elbow macaroni all work beautifully.
Make it richer: Stir in a bit of cream cheese for extra creaminess.

Olivia’s Cozy Kitchen Moment

This recipe came to life one cold, rainy Saturday when I couldn’t decide between chicken noodle soup and creamy pasta. So, naturally, I made both—in the same pot.

I remember my husband hovering near the stove, catching whiffs of the Cajun spice and saying, “What is that smell?” in the best way possible. One spoonful later, he was sold. This cajun soup has since become our go-to when we want something that feels indulgent but still fits into a real-life weeknight.

What to Serve with Spicy Pasta Soup

This soup is plenty hearty on its own, but if you want to make it a meal to remember:

Crusty garlic bread or cornbread
A crisp side salad with ranch or vinaigrette
Roasted green beans or broccoli
Iced tea or a chilled glass of white wine

Don’t forget the extra parmesan on the table—you’ll want it.

How to Store and Reheat

Store: Cool leftovers and refrigerate in an airtight container for up to 3 days.
Reheat: Warm gently on the stovetop or in the microwave, adding a splash of stock or cream if it thickens.
Freeze: Best without the pasta (it can get mushy). Freeze the base, then add fresh pasta when reheating.

FAQs

Can I use rotisserie chicken?

Yes! Just skip the skillet step and stir shredded rotisserie chicken into the soup at the end.

Is it really spicy?

It has a mild kick. Reduce Cajun seasoning or use a mild version if you’re sensitive to spice.

Can I make it dairy-free?

You can try using coconut milk or a dairy-free cream alternative and skip the parmesan or use a vegan version.

What other protein can I use?

Shrimp or sausage would also be delicious and very Cajun-approved!
